The answer to all gout and gall stones, regardless of blood type and personal genetics, is a ketogenic diet: high, 80+% fat ( a few percentage of which is equal amounts of omega 3 and omega 6 fats and the rest any combination of omega 9 and saturated fats); moderate, 15 % protein (half of the body protein is formed from collagen which is made up of 3 amino acids and is found in skin, hair, tendons, ligaments, all connective tissue, the outer layer of all the larger bones -- all the meat parts that most people throw out); and low, 5 % carbohydrates from green leafy vegetables including cruciferous which are mostly steamed. No grains, no refined sugar, minimal fruits, no chemicals, no excess omega 6 fatty acids, no msg. In your, Paul's, case it will have one drawback -- you will lose weight. Dr. Berg in your video selection is a great reference. Finally, vegan diets are good and useful and healthy for about 30 days only because they are detoxifying diets whose good effects are exhausted after that. Then they become slow starvation diets good for fungi, bacteria, and few animals.
